Alumina brick is a type of refractory brick that is made from high-grade alumina (AI2O3) and other raw materials. It has high refractoriness, excellent thermal stability, and good resistance to chemical erosion and mechanical wear.
Alumina bricks can be divided into two types based on their alumina content: high-alumina brick and low-alumina brick. High-alumina bricks typically have an alumina content greater than 48%, while low-alumina bricks have an alumina content between 30% and 48%.
Alumina bricks are widely used in various high-temperature industrial applications, such as in steel-making furnaces, glass tanks, cement kilns, and petrochemical reactors. They are also used in incinerators and power plants as insulation or protective lining materials.
The properties of alumina bricks can vary depending on the manufacturing process, raw materials used, and the specific application requirements. Some common properties of alumina bricks include high refractoriness, excellent thermal shock resistance, good chemical resistance, and high mechanical strength.
Overall, alumina bricks are known for their superior quality and durability in high-temperature environments, making them a popular choice for a wide range of industrial applications.
